If the Republicans maintain control of the House and Senate after the midterms, president Trump will demand the disclosure of the ObamaGate documents now being withheld from Congress by conflicted Jeff Sessions, and if the Republicans lose the control of the House, the president will even fire Sessions for withholding the documents, after Trump, who heads the executive branch, will have authorized the publication of those documents, so Sessions is on limited time as attorney general, time enough for him to come correct to save his job (the same applying to Rosenstein).
